Tweepy does not let me run api.get_user with a list of users and also not on a single person

api = tweepy.API(auth)
userID_list = ["elonmusk", "BarackObama"]
for userxyz in userID_list:
user_info = api.get_user(userxyz)
name = user_info.name
description = user_info.description
location = user_info.name.location
followers_count = user_info.followers_count
friends_count = user_info.friends_count
Writes this Error:
Traceback (most recent call last):

TypeError: get_user() takes 1 positional argument but 2 were given

API.get_user only accepts a single user as a user_id or screen_name keyword argument.

Get artist name

I'm trying to get the names of my top 3 artists of last week with pylast (https://github.com/pylast/pylast) but I run into an error or get I get None as a result and I don't see what I'm doing wrong. pylast is a Python interface to Last.fm.
My code:
import pylast
API_KEY = ""
API_SECRET = ""
username = ""
password_hash = pylast.md5("")
network = pylast.LastFMNetwork(api_key=API_KEY, api_secret=API_SECRET, username=username, password_hash=password_hash)
user = network.get_authenticated_user();
weekly_artists = user.get_weekly_artist_charts();
# Keep the first three artists.
del weekly_artists[3:]
# Print the artist name and number of songs(weight).
for weekly_artist in weekly_artists:
artist,weight = weekly_artist
print (artist.get_name())
print (artist.get_correction())
artist.get_name() returns
None
artist.get_correction() returns
Traceback (most recent call last):
File "G:\projects\python\lastfm_weekly\lastfm-weekly.py", line 28, in <module>
print (artist.get_correction())
File "C:\Users\..\Python\Python36-32\lib\site-packages\pylast\__init__.py", line 1585, in get_correction
self._request(self.ws_prefix + ".getCorrection"), "name")
File "C:\Users\..\Python\Python36-32\lib\site-packages\pylast\__init__.py", line 1029, in _request
return _Request(self.network, method_name, params).execute(cacheable)
File "C:\Users\..\Python\Python36-32\lib\site-packages\pylast\__init__.py", line 744, in __init__
network._get_ws_auth()
AttributeError: 'str' object has no attribute '_get_ws_auth'
What am I doing wrong?

Here is a quick and dirty solution, i'm sure someone will provide something better but i just installed the package to test and it works.
network = pylast.LastFMNetwork(api_key=API_KEY, api_secret=API_SECRET)
artists = network.get_top_artists()
del artists[:3]
for i in artists:
artist, weight = i
print('Artist = {}. Weight = {}'.format(artist, weight))
I'm not really familiar with the package, I just installed it to help out with this but I do wonder what "get_name()" and "get_correction()" are as they're not in your provided code.
If they're not functions you created / are defined within your code then I'd look there for the problem.
Also, you're authenticating the user but the documentation explicitly states you don't need to unless you're writing data.

Django create_or_update model attribute command works fine but update fails

I am trying to write a CSV helper that reads the CSV file and updates or creates fields in the model. The create_or_update query is working fine, but it is only creating not updating. On changing the create_or_update to update it throws an error. The code of the CSV helper is :
def insert_books_from_dictionary(data):
category, created = Category.objects.update_or_create(name=data['category'])
sub_category = None
if data['sub_category'].decode('utf-8') != '':
sub_category, created = SubCategory.objects.update_or_create(name=data['sub_category'], category=category)
publisher, created = Publisher.objects.update_or_create(name=data['publishers'])
# convert strings to float
# ToDo : Fix constraints and create a function
# to handle data check and conversion
try:
price = float(data['mrp_price'])
except ValueError:
price = 0.0
pass
try:
pages = float(data['pages'])
except ValueError:
pages = None
pass
isbn_13_str = str(data['isbn_13'])
isbn_10_str = str(data['isbn_10'])
image_url_str = str(data['image_url'])
binding = 1 if data['binding'] == 'Hardboard' else 2
book, created = Book.objects.update(title=data['title'],description=data['description'], pages=pages, binding=binding, price=price, category=category,sub_category=sub_category, edition_and_year=data['edition_and_year'],
isbn_10=isbn_10_str, isbn_13=isbn_13_str,image_url=image_url_str)
book.publishers.add(publisher)
authors = re.split(",", data['authors'].decode('utf-8'))
for author in authors:
author, created = Author.objects.update_or_create(name=author.strip())
book.authors.add(author)
return dict(book_id=book.id)
It throws the following error:
Traceback (most recent call last):
File "common/util/upload.py", line 18, in <module>
uploadbooks = book_upload(old_file, newfile)
File "common/util/upload.py", line 12, in book_upload
insert_seller_books_from_dictionary(req_data)
File "/home/subhajit/textnook/common/util/csv_helper.py", line 132, in insert_seller_books_from_dictionary
book_id = insert_books_from_dictionary(data)

isbn_10=isbn_10_str, isbn_13=isbn_13_str,image_url=image_url_str)
TypeError: 'long' object is not iterable
On changing update to create the error is no more. How do i resolve this issue?

in
book, created = Book.objects.update(title=data['title'],description=data['description'], pages=pages, binding=binding, price=price, category=category,sub_category=sub_category, edition_and_year=data['edition_and_year'],
isbn_10=isbn_10_str, isbn_13=isbn_13_str,image_url=image_url_str)
you are using update, not update_or_create
Book.objects.update updates only and returns the number of rows affected, which is the 'long' object is not iterable python complains about, since it has to assign its elements to the tuple book, created

I can't access an activity on Strava API using Python

I'm trying to access data for an individual ride using the Strava API but when I add the ride ID I get an error. Essentially I'd like to be able to access things like distance and times and see this as the first step but I can't pull back much information on a single ride. Here is the code and error:
from stravalib.client import Client
client = Client(access_token='My token here')
athlete = client.get_athlete() # Get John's full athlete record
print("Hello, {}. I know your email is {}".format(athlete.firstname, athlete.email))
# "Hello, John. I know your email is john#example.com"
activities = client.get_activities(limit=10)
assert len(list(activities)) == 10
#View activities
for x in activities:
print (x)
#<Activity id=270828720 name='Evening Ride' resource_state=2>
#<Activity id=270590277 name='Morning Ride' resource_state=2>
#<Activity id=270577804 name='Evening Ride' resource_state=2>
#<Activity id=270137878 name='Morning Ride' resource_state=2>
a = client.get_activity(270137878)
#Traceback (most recent call last):
# File "<ipython-input-22-a7e56786804d>", line 1, in <module>

# raise AttributeError("Error setting attribute {0} on entity {1}, value: {2!r}".format(k, self, v))
#AttributeError: Error setting attribute photos on entity <Activity id=270137878 name=None resource_state=3>, value: {'primary': None, 'count': 0}

Did you get an answer to this? The issue was a change to the Strava API V3 which added photos, and stravalib hadnt been updated to reflect this -

Its been fixed now

Key Error on python & App Engine

I am developing an application on App Engine and Python. This app is meant to create routes to several points in town. To create this routes, I invoke a request to an Arcgis service. Once that is done, I need to check the status of the request and get a JSON with the results. I check these results with the following method:
def store_route(job_id, token):
import requests, json
#Process stops result and store it as json in stops_response
stops_url = "https://logistics.arcgis.com/arcgis/rest/services/World/VehicleRoutingProblem/GPServer/SolveVehicleRoutingProblem/jobs/"
stops_url = stops_url+str(job_id)+"/results/out_stops?token="+str(token)+"&f=json"
stops_r = requests.get(stops_url)
stops_response = json.loads(stops_r.text)
#Process routes result and store it as json in routes_response
routes_url = "https://logistics.arcgis.com/arcgis/rest/services/World/VehicleRoutingProblem/GPServer/SolveVehicleRoutingProblem/jobs/"
routes_url = routes_url+str(job_id)+"/results/out_routes?token="+str(token)+"&f=json"
routes_r = requests.get(routes_url)
routes_response = json.loads(routes_r.text)
from routing.models import ArcGisJob, DeliveryRoute
#Process each route from response
processed_routes = []
for route_info in routes_response['value']['features']:
print route_info
route_name = route_info['attributes']['Name']
coordinates = route_info['geometry']['paths']
coordinates_json = {"coordinates": coordinates}
#Process stops from each route
stops = []
for route_stops in stops_response['value']['features']:
if route_name == route_stops['attributes']['RouteName']:
stops.append({"Name": route_stops['attributes']['Name'],
"Sequence": route_stops['attributes']['Sequence']})
stops_json = {"content": stops}
#Create new Delivery Route object
processed_routes.append(DeliveryRoute(name=route_name,route_coordinates=coordinates_json, stops=stops_json))
#insert a new Job table entry with all processed routes
new_job = ArcGisJob(job_id=str(job_id), routes=processed_routes)
new_job.put()
As you can see, what my code does is practically visit the JSON returned by the service and parse it for the content that interest me. The problem is I get the following output:
{u'attributes': {
u'Name': u'ruta_4855443348258816',

The actual JSON returned has a lot more of info, but i just wrote a little portion of it so you can see that there IS a 'geometry' key. Any idea why I get this error??
